My dad constantly complains of leg weakness, says it's mostly in his thighs. He's walking less and less because of it, and walks with a very slow, shuffled step. When he goes to any store he seeks out a motorized cart to avoid walking much. He uses a cane for most walking otherwise. When we discussed this with his dr several months back the dr prescribed physical therapy, my dad went to that for 3 months or so, but says it was of no help. He stills goes to exercise 3 times a week, but we both know that's mostly socialization time. We recently added vitamin D and potassium supplements to his meds to see if that might help. This is really impacting his quality of life more than anything else, and has me wondering how much longer I can keep him in his house, as I know it's increasing his fall risk.
